Aguascalientes valley, located in the central part of
México, is affected for a land subsidence process triggered by
groundwater withdrawal since the 1980's. Currently, the
occurrence and the reactivation of surface faults and earth fissures due to
differential subsidence, is the main concern for government bureaus dealing
with urban planning, beca...
Land subsidence is an anthropogenic hazard triggered by different causes,
one of them is groundwater overexploitation over aquifer systems composed
for granular compressible sedimentary fill. One of the effects of this
phenomenon is the generation and reactivation of ground failures, becoming
risk points for aquifer pollution through the fast infil...
Land subsidence due to groundwater withdrawal has been
developing in the Aguascalientes Valley since the 1980's.
Even though the affected area is close to 900 km2, and the sinking velocity
is up to 10 cm yr−1 in some zones, the main concern for valley inhabitants
and local government is the occurrence of subsidence-related cracks and
failures, whic...
In the Aguascalientes valley, middle Mexico, the demand of groundwater from the local aquifer system was suddenly increased after the late 1970s. Since then, several related problems have been occurring or become critical such as land subsidence, ground fissuring, and low-magnitude earthquakes. The most recent data of vertical deformation from PSIn...
The impact of faults and fissures (discontinuities) on the groundwater flow
has become important in several parts of the world because the
heterogeneous and anisotropic distribution of permeability in fault zones is
difficult to characterize. Based on this, we propose an analysis of patterns
of parameters measured in groundwater, under the premise...

Surface failures have been observed in the valley of Aguascalientes since the
early 1980's. Although, groundwater pumping began in the early 1950's but
became intensive until the late 1970's, when many of the surface failures
appeared. For this reason, surface deformation (surface failures and land
subsidence) has been associated to groundwater wit...
Interferometric Synthetic Aperture Radar (InSAR) has become a valuable tool
for surface deformation monitoring, including land subsidence associated
with groundwater extraction. Another useful tools for studying
Earth's surface processes are geophysical methods such as
Gravimetry. In this work we present the application of InSAR analysis and
gravim...
In this study we investigate different aspects of land subsidence and ground
failures occurring in the west portion of Chapala lake basin. Currently,

The Eglington fault...
Land subsidence and earth fissuring can cause damage in semiarid urbanized valleys where pumping exceeds natural recharge. In places such as Las Vegas Valley (USA), Quaternary faults play an important role in the surface deformation patterns by constraining the migration of land subsidence and creating complex relationships with surface fissures. T...
Overpumping in Las Vegas Valley has caused an increase in effective stress and the accumulation of strain in critical zones. As a consequence of this stress-strain configuration, surface deformation expressed in the form of earth fissures and land subsidence has been occurring most commonly in zones adjacent to quaternary faults. The Eglington Faul...
Earth fissuring associated with subsidence from groundwater pumping is problematic in many arid-zone heavily pumped basins such as Las Vegas Valley. Long-term pumping at rates considerably greater than the natural recharge rate has stressed the heterogeneous aquifer system resulting in a complex stress-strain regime. A rigorous artificial recharge...
Fracturing of clayey fluvial and lacustrine deposits has become a major problem in several cities of central Mexico. The available data reveals the coexistence of several factors determining fracturing at different scales. As main factors we analyze the variation in compressibility of sediments causing differential deformation and withdrawal of gro...
Land subsidence and subsequent earth fissuring are common characteristics in over-pumped arid to semiarid basins such as Las Vegas Basin (LVB). Both phenomena are consequences of stress-strain adjustments during or after groundwater withdrawal, resulting in strain accumulation and further deformation on or near the land surface. Land subsidence occ...
Land subsidence in the Valley of Querétaro is an active phenomenon that has been associated to extensive groundwater withdrawal. However, a fault-fracture system affecting the city of Queretaro is aligned with north-south striking regional faults suggesting that buried fault scarps determine the geometry and propagation of fractures. Likewise, faul...
Land subsidence in the Chalco Valley, near Mexico City, is caused by the consolidation of the upper aquitards, which consist mainly of saturated silty- clayey sediments interbedded with sandy lenses of volcanic ash. Detailed characterization of the physical and mechanical properties of the top 15 m of the sequence was performed. Laboratory analyses...
